Plastic insert

The heater lever just beside the hand brake lever doesn't work well on VW 1302 Super Beetle, easily returns to original closed position because of loss of adequate slipping resistance.
Careful checking revealed the fundamental reason was destruction of engineering plastic insert producing slipping resistance to keep the lever at the desired position connected with the door in heat exchanger in the rear muffler.
Similar alternative material of polyacetal plastic with 2,5mm thickness was found, the result would be a later description.

As I guess counterclockwise rotation of automatic choke module could prolong the interval of choke effect preventing idle stop because of lack of warming up by choke device.
The lettering Solex should be parallel to the ground is the matched position in the atmospheric condition these days.
At lunch break time the heater lever plastic was inserted with alternative engineering plastic material resulting in good success.
Though the inconveniences in the Super Beetle are reduced one by one and day by day, comfort while driving would not reach to the revel of those with the automobile nowadays.
